A sewer hose that withstands cold weather


By Chris Dougherty
Chris Dougherty is a certified RV technician. Here is an article he wrote while he was serving as’s technical editor.

RVing in winter has its challenges as well as rewards. One major challenge is trying to keep liquids liquid, whether that be fresh water or waste.
Having been a fulltimer in the Northeast for ten years, I became an expert at making RVs handle the frigid winters. I went through many sewer hoses, breaking them all. I wish I had this one from Camco back then.

Most RV sewer hoses are designed for warm weather use only. Once the temperature falls below freezing, the plastics crack and the hose is done. In addition, most hoses use spring steel to form the ridges which may work fine under occasional warm weather use, but once the use becomes more constant or extreme, the hoses will experience failure.

Camco has designed a hose, the RhinoExtreme, that it claims will survive to -44 degrees F, and won’t crush, rust or crack. The hose is also abrasion-resistant, and can even be driven over and return to its original shape. It can do this because of its triple-TPE vinyl layering, and its polyolefin wire core, which won’t dent or rust, always returning to its original shape.

The hose kit comes complete with a 15-foot-long hose with pre-attached Rhino swivel connectors with four bayonet tabs instead of the usual two for more sound connections, a translucent elbow, reusable locking rings, storage caps and a universal campground sewer adapter. The set retails for around $60 on Amazon. In addition, a 10-foot extension is available for about $25.

It is important to note that no sewer hose, or rigid pipe for that matter, will prevent freezing and freeze-related damage. Use this hose only while dumping – black water followed by grey water for a rinse out – and make sure no liquid remains in the hose when you’re done.

Have you used this hose during the winter? Do you have another product you’re using for wintertime RVing that other RVers should know about? Please let us know by leaving a comment.

I worked in Olwein Iowa over a winter a few years ago and found that even though my RV could handle the cold, most (or all) campgrounds close late in October. I chose to find a mobile home park and put my camper there. I parked right over top of the water and sewer connections. I hard piped all my tanks together and ran to the sewer with heat trace on them. You can find fittings on that will convert from bayonet to 3″ PVC. I also paid almost $3K to have someone come out and skirt the camper with reusable snap-on insulated panels. Finally, a heat trace water hose rated down to -22 degrees. Put a little space heater under the camper. Never had an issue with freezing, but the cost (especially the electric bill) was astronomical. $400 a month plus, in addition, you will also pay for the other utilities + the lot rent. Wouldn’t recommend this for anyone unless you have the funds to pay for it and have the knowledge and where with all to do the work and maintenance.

I recently spoke with the folks at and they will be releasing a NoFreezeWasteHose for the RV and Tiny home market soon. They have sold these in the past for customized commercial orders with success and will now start serving the individual market.

If Chuck and Gail spent time in really cold weather for extended periods ( they would only if unavoidable) there sewer system would stand up to the weather because it was designed for extreme heat, as well as extreme cold.
In addition because their hose is always connected to the tanks outlet and has an ON/OFF valve built into the sewer inlet fitting, they have a couple of “dumping in extreme cold” choices.
1. Chuck or Gail (yes Gail dumps the holding tanks) can leave the hose in the weather without damage, or, 2 Extend the hose and dump the tanks, then return it to the water bay until the next time they need to dump. If they were faced with, or decided they liked extreme cold camping, they could have a water bay heater installed so the hose would not have frozen water in it. This would cost a lot less than heat tape on all external piping and is more effective.

Why would you use a sewer hose in freezing weather? Why wouldn’t you just dump the tanks when they are full and the weather is warmer?…..and when done dumping (about 5 minutes) put them away and not worry about the hose freezing? Really, screwing/unscrewing that sewer hose is no big deal!

We have been in the RV for nine months while we were traveling . Now we are in an RV Park for five months while our house is being built.
To answer your question why would you have your sewer hose connected all the time? We have had two weeks of temperature below 14 degrees for the lows. If you fill your holding tanks up, they will freeze and crack, so you have to empty frequently and wash with the grey water.

I am using the hose that you wrote about, stayed st Oak Hallow CG in Highpoint, NC. at temps of 13 plus the wind chill coming off the lake. Apparently didn’t get all the gray water out of hose and decided not to put it away. Yes it froze with ice chunks, put it in the car with the heat on high and in a couple of hours it thawed and no leaks today in 40 plus degrees.
